Chieftain LLC: West Seattle 4-Star Townhomes

  • Case Studies

Just northwest of the Junction, hidden behind mature trees, are six townhouses built by Chieftain LLC. By retaining existing trees, the houses look as though they have been in the neighborhood for years, while a modern façade gives away their newly built status. Ideally located within short walking distance to grocery stores, restaurants, and bars, these units have a walk score of 96. In addition to their walkability, they also have stepless entrances, gaining them some points for universal design.

Beyond accessibility and location, these units were able to obtain high energy savings. By incorporating blown-in fiberglass insulation in the exterior walls, a combination of spray foam and batts in the ceiling, ductless mini-splits, and a high efficiency gas tankless water heater, these units were able to obtain energy savings of 39.5% better than a code-built house. Extremely efficient appliances, including the refrigerator, washing machine, and dryer, help contribute to the energy savings, which will translate to dollar savings for the homeowners. Better-than-code windows will help keep the temperature comfortable year-round.

The project also used an abundance of locally produced material, including rigid insulation, framing lumber, sheetrock, cabinets, and windows. By making use of the concrete slab as a finish flooring on the main level, Chieftain was able to provide contrast to hardwood flooring on the remaining levels and keep the variety of materials used low. GreenGuard Gold stains keep the indoor air quality healthy for the homeowners.
